In the STAR experiment at the RHIC accelerator, collisions of proton and heavy-ion beams of different energies are studied in different configurations. In a significant fraction of the proton-proton collisions, the primary protons remain intact and are scattered at very small angles. These types of collisions take place mostly by exchanging the so-called Pomerons. As a result of such collisions, different final states can be produced in the central range of pseudorapidity. In this thesis we investigate the possibility of measuring $K^0$ mesons and $\Lambda^0$ baryons in the inclusive process of central production, $p + p \to p + p + K^0(\Lambda^0) + X$, in collisions recorded in the STAR experiment at the centre-of-mass energy of $\sqrt{s} = 510$~GeV. For the reconstruction of diffractively scattered protons, the Roman Pot detectors are used, while the decay products of $K^0$ or $\Lambda^0$ are registered in the central detector.
